If your an addicted one-armed bandit gambler, you have probably given a large chuck of money to the casino. Because of that loyalty and instead of blacklisting you, the casino charges a small fee to psychologically bore you away from the slots.

This done using the pervasive photo recognition and
ID 'loyalty' swipe cards implemented on the slots. Using past casino played statistics, the machine payback will be psychologically designed for the identified playing addict. If the computed payment plan is stuck to over a long period, the player should slowly become bored and withdraw from the game. It's the simple task of manipulating neurotransmitters to reset binding site sensitivity via external win and loss stimulation.

The casino would get kudos for physically helping addicted gamblers.
And of course, the casino always wins it's small take.

Uh, every slot machine already "charges a small fee", and
that is insufficient to discourage gambling. You are talking
about increasing the fee without increasing the chance of
reward --and what will happen is that the customer will go
to a different casino where the cost/reward ratio is
perceived to be better. You can't beat the Law of Supply
and Demand --someone will always offer the cost/reward
ratio that leads to the most profit from attracting the most
gamblers.

The player should win nothing at the machine, but, say, a
guaranteed 90% of deposited money should be returned to
him at the end of each month. No variation, no odds, no
risk. You put in 25 cents, you get back 22 cents.

Bandit machines take your money, may pay you some but entire take flows into your account. You may not withdraw from this account until a year has elapsed. At that time you may withdraw: the amount has increased by a % interest. The facility charges a small % for administering the account. Monies in the accounts are available for loan according to typical rules; you must go next door for that, undergo credit check, etc. This is not a casino, but a bank.

From your annos I don't think I have have explained my idea very well. [Voice] was the closest but the 22 cents is paid to you in a way that makes you bored. Little trickle wins or biggish pay-offs or any pattern in between depending on the player's psychology.

[vernon] If you get most of your money back (way more than house pay-offs) why would you go to another casino.
